What you want to ask is, what is the cause of the pole piece deviation problem in the lithium battery coating furnace? Reasons include uneven oven temperature, vibration or shock during transportation.
1. Uneven oven temperature: Uneven temperature distribution in the oven can cause the pole pieces to heat unevenly during the baking process, causing the pole pieces to deflect. This could be due to uneven heating elements inside the oven or poorly designed air ducts.
2. Vibration or impact during transportation: During transportation of the pole piece, if it is subjected to vibration or impact, it may cause the pole piece to deflect. This may be due to unreasonable equipment or transportation methods.
The process technology of lithium-ion batteries is very strict and complex. We cannot presentHere only briefly some of the main processes. (1) Special solvents and binders are used for mixing sludge with powder positive and negative electrode active materials respectively, and after high-speed uniform mixing, sludge-type positive and negative electrode materials are made. (2) Coating film: Apply the prepared suspension evenly to the surface of the metal foil, dry it, and make positive and negative electrode plates respectively. (3) The assembly is placed in the order positive electrode sheet - separator - negative electrode sheet - separator from top to bottom, and is rolled to form the battery pole core. Then the battery is completed by electrolyte injection, sealing and others. process. The assembly process creates the finished battery. (4) The chemical industry uses special battery charging and discharging equipmentto perform charge and discharge tests on finished batteries, inspects each battery and selects qualified finished batteries before leaving the factory.
